7 Claims.

invention is a chair particularly designed for obstetrical purposes.

An object of the invention is to provide a chair of this character whichisfoldable, and which is also so constructed as to permit the usethereof during actual labor, as well asfor examination purposes.

The invention, together with its objects and advantages will be bestunderstood from a study of-the following description, taken inconnection with the accompanying drawings, wherein:

Figure 1 is a perspective view of the chair, in one position."

Figure 2 is a similar view of the chair in a second position.

Figure '3 is a bottom plan view of the seat of the chair.

Figure 4 is a plan view of the back rest, and

Figure 5 is a plan view of an abdominal belt.

Referring to the drawings by reference numerals, it will be seen that inthe preferred embodiment thereof, the improved folding obstetrical chaircomprises a seat 5 supported by rear legs 6 andvfront legs I. The seat 5as shown is pro- 25 vided with an opening 8 of suitable edge contour andopening through the forward end edge of the seat. Opening 8 is providedto permit the performance'of vaginal examination, to take care ofsecretions; and to accommodate the child upon delivery thereof.

For supporting the seat to the horizontal, there are-provided rails 9having one end abutting the legs 6 and pivoted to v the legs 6 throughthe medium of brackets l0. At the free ends thereof the rails 9 areprovided with notches II to receive the ends of a rod I2 that connectsthe free ends of legs 1. Thus, by engaging the rod l2 in selectednotches ll, the' seat 5 may be supported at the desired angle to thehorizontal.

To secure the rod l2 in engagement with selected notches Il', each rail9 is provided witha retaining bar 28 secured at one end thereof to therail- 9 through the medium of an eye screw 29 clearly shown in 5 at thedesired angle and having a free end fashioned to provide a hook 30engageable with a keeper eye 3| provided substantially a continuation ofthe opening 8 whereby a relatively large opening is provided forexamination or delivery of the child. The footrest is preferably hingedto the legs I at the lower edge of the leg rest 14 as at 16.

The chair is also provided with a backrest l6 which includes a pair" ofside rails I1 pivoted at one end to brackets l8 provided at oppositesides of the seat 5 adjacent the rear of the seat. A back supportingplate 19 is supported between the sides I! of the backrest and isprovided in the lower edge thereof'with an opening 20 topermit'manipulation of the spine during childbirth. 1 i

Also extended between the upper ends of the sides'l'l of the backrestare spaced strips 2| of suitable fabric forming a rest for the head,while extended across the backrest adjacent the lower edge of the backsupporting plate I9 is a strip 32 of fabric which provides a yieldingsupport for the back of the patient adjacent the base of the spinal'column.

Forsecuring the backrest 16 at the desired position of adjustment thereis provided a U- shaped brace 22, the legs of which at the open end ofthe U are pivoted to the sides ll of the backrest intermediate the endsof said sides. At the closed end of the U the brace member 22 isengageable in notches 23 provided therefor in the rear edges of the rearsupporting legs 6. Thus, it will be seen that with the brace member 22engaged in the notches 23 as shown in Figure 1, the backrest I5 issupported at a suitable angle to the perpendicular for supporting theback of the patient assuming a sitting posture on the chair.

For supporting the back IS in a substantially horizontal position, brace22 is swung to the position shown in Figure 2 so that the lower orclosed end of the brace rests on the floor. Thus with the back l6 shownin the position in Figure 2, the person may occupy the chair in areclining position.

The sides I! are also provided with suitable brackets 24 with which areengaged the straps 25 provided in pairs on the opposite ends of anabdominal belt 26. The belt 26 is to be used during childbirth, and whenso used, serves tolift the abdomen, thus bringing the axis of'the uterusin line with the birth canal and corrects the posterior position of thecervix; while at the same time, the belt will'exert a pressure over theupper portion of the abdomen for aiding the expulsive forces'of labor.

There are also provided at opposite sides of self, andj'at thesametimefacilitate examination,

direction of the patient, and assistance to the patient by the attendantduring labor. Also, as clearly shown in Figures 1 and 2, to

secure the supporting brace 22 engaged with the notches 23 there issuitably mounted-on one of the legs 6 a retaining hook 33 that'engagesthe closed end of the brace 22 ina 'in'anner shown in Figure 1, wherebythe back of the chair is: positively secured in the position shownin'Figuiel. When tnot in use, the chairmay ""be readily folded" as isthought t'o*be;"apparent and in' a' folded conditionwill require butrelatively small stora'ge space."
